~Koji Uehara 1975 (Cubs 2017)
The 42-year-old reliever was far from his prime when he joined the Cubs after a successful stint with the Boston Red Sox. Nevertheless, he managed to appear in more than 40 games, posted a sub 4 ERA (3.98), and even saved 2 games for the Cubs.
~Duane Underwood 1994 (Cubs 2018-present)
Duane was the second round pick of the Cubs the first year of the Epstein/Hoyer era. He got his first taste of big league in action in a June 2018 spot start. He pitched well, though he lasted only four innings and took the loss. His only blemish was giving up a homer to KiKi Hernandez of the Dodgers.
~John Upham 1941 (Cubs 1967-1968)
Upham pitched and played outfield for the Cubs in two brief big league trials. As a pitcher, he was a decent hitter. As an outfielder, he was a decent pitcher. His lifetime ERA in the big leagues was 5.40, and he never got an extra base hit. In fairness to Upham, he did bat .293 over his nine year minor league career. (Photo: Topps 1967 Baseball Card)
~Bob Usher 1925 (Cubs 1952)
Bob was one of the players acquired in the Smoky Burgess trade in the winter of 1951. He got exactly one plate appearance for the Cubs. On April 26, 1952, he pinch hit for Cubs starter Turk Lown and walked. After that, they shipped him out to the minors. It took Usher five years to return, and when he did, it wasn’t for the Cubs. He probably had the best year of his career for the 1957 Washington Senators.
~Cubs Usher (Bruce Bohrer)
Bruce was a Cubs usher for nine seasons (2003-2011), and he’s also the author of this great book, available in the Just One Bad Century store.
